Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:
.The required hitch ball size is stamped on
most trailer couplers. Most hitch balls
also have the size printed on top of the
ball.
. Choose the proper class hitch ball based
on the trailer weight.
. The diameter of the threaded shank of
the hitch ball must be matched to the ball
mount hole diameter. The hitch ball
shank should be no more than 1/16”
smaller than the hole in the ball mount.
. The threaded shank of the hitch ball must
be long enough to be properly secured to
the ball mount. There should be at least 2
threads showing beyond the lock washer
and nut.
Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the hitch
receiver. Choose a proper class ball mount
based on the trailer weight. Additionally, the
ball mount should be chosen to keep the
trailer tongue level with the ground.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on the
receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer to
distribute the tongue weight (hitch weight)
of your trailer. Many vehicles cannot carry
the full tongue weight of a given trailer, and
need some of the tongue weight transferred
through the frame and pushing down on the
front wheels. This gives stability to the tow
vehicle.
A weight-distributing hitch system (Class IV)
is recommended if you plan to tow trailers
with a maximum weight over 5,000 lbs
(2,267 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge brakes.
If you are considering use of a weight-
distributing hitch system with a surge brake-equipped trailer, check with the
surge brake, hitch or trailer manufacturer
to determine if and how this can be done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.
With the ignition switch in the ON
position and the doors closed, allow the
vehicle to stand for several minutes so
that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that the
front bumper height is within 0 - .5
inches (0 - 13 mm) of the reference
height measured in step 2. The rear
bumper should be no higher than the
reference height measured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If
the rear bumper is higher than the
